Abstract

With the rapid development of the advanced manufacturing industry driven by China‘s national projects such as aerospace, rail transit, nuclear energy, and offshore drilling, the surface, and interface of key parts of the equipment are increasingly facing more extreme and complex environments such as high temperature, heavy load, and intense corrosion. Therefore, it is urgent to develop new surface coating technologies and advanced coating material systems. With the advantages of thermal spraying and laser cladding, laser hybrid thermal spraying technology possesses unique merits for the preparation of high-performance ceramic-based composite coating with low defects and strong bonding, which can significantly improve the wear, corrosion, and oxidation resistance of equipment components. In this review, five parts are classified according to the coating material systems and preparation process.

Key words
